What are these brand metal detectors?

You don't read much about them

Are they good or copies of other detectors?

Dement detectors are based on vintage Fisher VLF 555 detectors - with minor modifications only.

Most Armand detectors are based on vintage CSCOPE DIY desing called 'K5000'. Not sure what was modified/improved/redesigned in electronics during years of production. One apparent alteration is the LED bar graph instead of a needle meter.

Kind of suspected they were just based on some vintage VLF/TR type machines after reading about them at the websites and watching the videos.

What about DRS detectors from Germany, very sketchy info. Not much of anything posted on the German forum, except possibly being manufactured in Turkey.
